To Ml whom it may concern:

Be it known that I, PAUL BENARD, a citizen of France, residing at No. 8Place Auban Moet, Epernay, Marne, France, have invented new and usefulImprovements in Devices for Lighting by Electricity Reversed Gas-Burners, of which the following is a specification. v I

This invention has for its object improve ments in devices for lightingreversed gasburners, in which a platinum coil brought to a red heat bythe passage of an electric current is employed for the purpose oflighting the burner. These improvements consist in placing the platinumcoil outside the caloric focus formed by the light-burner, so as toprotect it therefrom though the gases are concentrated in the spacewhere said coil is arranged as soon'as the burner is opened, whereby thelighting is insured under normal conditions. By these means the rapidspoiling and wearing of the lighting-coil is avoided.

The annexed drawings show a form of construction of the improvementsembodying this invention.

Figure 1 is an elevation view of a reversedburner provided with thelighting device and seen from the side of said device. Fig. 2 is a sideview of the burner. Fig. 8 is a plan view of the supporting-plate onwhich the coil-holder is fixed. Figs. 4 and 5 represent in front andside views the coil-holder.

The reversed burner comprises a Bunsen (1, arranged at the upper part, aporcelain reversed cone b in the central part, and an outlet gas-nozzle0, arranged at the lower part. A metal plate (Z, provided with a centralopening 0, is fixed between the Bunsen and the body of the burner. Tothis plate are attached arms f, which support downward a ring 9concentric with the burner. The platinum coil 8 is arranged between twoarms 1 and 2 of the coil-holder 3, and the latter is secured to theplate d by means of lugs h and "L, cut from'said plate and which areraised up to form hooks. A wire-gauze covering 71. is placed about theburner on the side of the coil, as shown in the drawings. The covering7, which is arranged vertically, extends only up to the top of the plate(1, to whlch it is hooked by means of the tongue Z of said plate, whichis turned down and engaged in the opening m of the covering. Downwardthe covering extends to the ring g, on which it rests, and sidewise itextends to two adjacent arms f. A sort of a chamber limitedSpecification of Letters Patent.

by the plate d and the covering 1c is thus formed, and it is in thischamber that is hung the coil 8. A second plate or screen p,placed overthe burner, is arranged obliquely above the lower openings of saidburner, so as to force in all cases the gas coming out from theseopenings when the burner is opened to gather in the chamber where thecoil is hung. Finally, a wire-gauze r surrounds for a large .part theBunsen, so as to prevent the flame produced during the lighting fromfiring the Bunsen itself. With thisconstruction it is possible ofarranging the reversed burner more or less inclined to the vertical orquite vertical, and in all cases when the gas-cock will be opened almostall the gas escaping from the burner will be concentrated in the chamberwhere the platinum coil is placed. If at this moment the electriccurrent has been opened, the coil being brought to a red heat in themass itself of the gas the lighting will be insured.

It will be understood that as soon as the lighting is effected the coil8, placed toward the top of the apparatus and behind the protecting-capformed by the cone, will be in no way subjected to the flame or to thestrong heat of the burner, so that one will have no rapid wearing tofear. 7

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A device for lighting by electricity reversed gas-burners, comprisingin combination with a Bunsen and a reversed cone of porcelain placedbetween the Bunsen and the lower outlet gasopenings, a metal plate (1the burner, a support 3 fixed on said plate, two current-conductors 1and 2 carried by said plate, a platinum coil 8 fixed at the lower end ofthe two conductors between the plate d and the reversed cone, awire-gauze covering 76 placed about the burner on the side of the coil,outside the latter, and extending upward to the plate d, substantiallyas described and for the purpose set forth.

2. A device for lighting by electricity reversed gas-burners, comprisingin combination with a Bunsen and a reversed cone of porcelain placedbetween the Bunsen and the lower outlet gas-openings, a metal plate (1fixed between the Bunsen and the body of the burner, a'support 3 fixedon said plate, two current-conductors 1 and 2 carried by said plate, aplatinum coil 8 fixed at the lower end of the two conductors between theplate d and the reversed cone, a wire-gauze covering 7c placed about theburner on the side of the coil, outside the latter, and extending upwardto the plate d, and a screen p arranged obliquely on the burner abovethe lower outlet gas-openings, and the upper edge of which is on theside of the covering 70, substantially as described and for the purposeset forth.

8. A device for lighting by electricity reversed gas-burners, comprisingin combination with a Bunsen and a reversed cone of porcelain placedbetween the Bunsen and the lower outlet gas-openings, a metal plate dfixed between the Bunsen and the body of the burner, a support 3 fixedon said plate, two current-conductors 1 and 2 carried by said plate, aplatinum coil 8 fixed at the lower end of the two conductors between theplate d and the reversed cone, a wire-gauze covering 74' placed aboutthe burner on the side of the coil, outside the latter, and extendingupward to the plate d, a screen 29 arranged obliquely on the burnerabove the lower outlet gas-openings, and the upper edge of which is onthe side of the covering 70, and a second wire-gauze r placed about theBunsen, sub stantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PAUL BENARD.
